Purchase the option or the upgrade you need. When placing the order, please indicate the original serial number that you need to upgrade/update.

As soon as the payment is received we will generate an upgrade serial number.

Go to the computer with the original serial number still activated

Add the serial number to the current serial number and activate it.

Note that you will always need to have the 2 serials activated: the original one and the upgrade serial number. So for example if you had a serial number for MovieRecorder 2 and purchased an upgrade to MovieRecorder 3, your license window should look like this:

Note at the top right that the license window always tells you the number of channels that are authorized. In the example above, you have 1 channel authorised, so you'll be able to enable one source in MovieRecorder 3.
